The demand for cement and concrete is highly increasing due to urbanization and increase in the world's population. Portland cement production releases substantial amounts of greenhouse gases (GHGs) into the atmosphere, which is causing the climate change. Furthermore, cement and concrete industries consume a large amount of energy and natural resources. Therefore, it is important to develop new methods to overcome the challenges created by these products. The purpose of this paper is to make a review of opportunities for achieving sustainable cement and concrete industry. Using supplementary cementitious materials as partial replacement of cement, is one of the main opportunities to reduce the amount of cement usage in concrete. The paper also reviews other factors that can increase sustainability of cement and concrete industry, which include utilizing recycled aggregates and other recycled materials, optimize concrete mix design, structural optimization, replacement of fossil fuels, carbon capture and storage, increasing durability of concrete, extending the service life of existing infrastructures, water management, implementing regulations as well as other opportunities such as carbonation, alternative binders, energy storage and energy harvesting. These solutions can play an important role in producing more sustainable concrete and thus, reducing GHG emissions, conserving natural resources, decreasing wastes and conserving energy. 

In recent years, recycled materials mostly available in abundant quantities in local agricultural fields are considered as potential constituent material for concrete production. Also, cement production emits many toxic gases in the atmosphere, which causes environmental pollution and greenhouse gases. Thus, recyc;ed materials, such as fly ash (FA), wheat straw ash (WSA), and maize corn ash (MCA) are condered as cementitious binders in concrete for sustainable development. This study aims to determine the engineering properties of concrete with a ternary blend of fly ash, wheat straw ash, and maize cob ash. A total of 73 concrete cubes, 42 reinforced concrete prisms and 42 concrete cylinders were cast to examine mechanical properties of concrete at 7, 28, and 56 curing days. At 28 days (maturity period), the experimental results showed an increase in compressive, tensile, and flexural strength by 12.28%, 9.33%, and 9.93%, respectively, at 9% substitution of ternary cementitious materials (TCM). However, the density of concrete was reduced by 9.92%, with an increase in the TCM content after 28 days. Moreover, the modulus of elasticity was improved by 14.23% with an increase in the content of TCM up to 18% after 28 days, and drying shrinkage of concrete was reduced with the introduction of TCM content after 50 days. However, the workability of fresh concrete decreased as the percentage of TCM increased. Results of this study proved that agricultural materials investgated could be good fit as binder in cementitious composites.
